TO ALL WHOM IT MAY CONCERN:

Be it known that we, JOHN S. HENRY and ABRAHAM II. REIST, of Manheim, inthe county of Lancaster, and State of Pennsylvania, have invented a. newand uscful'lmprovemcnt on a Tool for Cutting off Bolts, Rivets, &.c.;and we do hereby declare that the following is a full, clear, and exactdescription of the construction and l operation-of the same.l referencebeing had to the accompanying drawings, making a part of thisspecification,

in Whichi l Fig-ure 1 represents the tool drawn apart to open the jaws.

Figure 2, the same in part, showing the under side Hush, with theinserted steel jaws D E closed.

Figure 3 is a view of the same on the edge.

The nature of our invention is to apply our cutter from the side of thebolt or rivet, and to dispense with the loop closing both sides of thejaws, and in the mode of the attachment and action of thejaws.

The drawings so clearly show the construction, and its application andoperation are readily understood, so i as to enable any one skilled inthe art to make and use our invention.

l The two handles or levers A. B, of any desired size and strength, moveen pivots R and R. The arm or lever-handle A is terminated by anenlarged and slotted head, H. This head is connected by a stout pivot,R', to the handle B, which latter is cut out for the reception of astout steel chisel-bit or cutter, E. This cutter has a shoulder, e, andthe blade E slides under a. strong loop, L, which loop contines theaction of the blades, so

l as to bring their cutting-edges squarely together. The jaw or blade DYis set into and across the round head or end of the piece C, and securedby a dove-tail insertion on screw-headed bolt b, countersunk on thelower side,

i as is the loop L on the extended arm of B, in order that beth blades DE and appliances lie ush or atly around the rivet to be cut. The pieceC, with cutter D, is also connected, atits lower end, by a stout pivotor pin, R, to the slotted head II. i l

These pivots R R are the fulcra upon which the tool moves and the bladeshave their action, and by drawing the lever-handles apart the jaws open,so that the tool can beinserted from the side to embrace the bolt orrivet to be severed. By bringing the lever-handles together the jawbsmove together, and will make a clean cut. Both blades act in concert,there being a twofold action. i

A tool on this plan gives the most satisfactory results, and it isbelieved to be a. decided improvement over` that ef Mr. Guthries,which,llike Mr. Johnstons, operates the one cutter between parallelbars, within a loop of the prolonged sides. The eogs in thelever-handle, and on the rack-like arm of the movable cutter, as well.as the eccentric action, are sooner rounded by wear than the xed pivotswe use in the manner shown, and our tool can be inserted below a nutthat is battered, when too large to allow the loop used in the casesreferred to for being slipped over it, so as to get under -it with theblades. We are not aware that a tool arranged in the manner shown wasever before used.

What we claim as our invention, is

The combination and arrangement of the jaws D E, unobstructed on oneside, when said jaw D is connected with piece C, with its fixed loop L,and pivot-connection toiII, and the jaw or cutter E, with its shouldere, is er the end of the prolonged handle or lever B, combined andoperating in the-manner and for the purpose specified.
